[PATCH] ref-filter: mark some file-local symbols as static

Hi Olga,

If you need to re-roll your 'ot/ref-filter-object-info' branch,
could you please squash this into the relevant patch (commit c5d9a471d6,
"ref-filter: use oid_object_info() to get object", 2018-07-09).

[Both sparse and my static-check.pl script are complaining about
the 'oi' and 'oi_deref' symbols.]

Thanks!

ATB,
Ramsay Jones
